PRESBYOPIA OPERATION IN BARCELONA
What is presbyopia?
The eye focuses images with the help of two lenses: the cornea and the crystalline lens. The cornea is a fixed lens that cannot vary in shape or size. The crystalline lens, on the other hand, is a lens that is attached to a muscle that allows us to vary its shape and, therefore, its power. Thanks to these movements, we can focus both near and far images. From the age of 45, the crystalline lens hardens and loses elasticity. The consequence is that the muscle responsible for changing its shape (ciliary muscle) is unable to do so and the ability to focus – or accommodate – is lost.
The more distant the images are, the more relaxed the ciliary muscle is, but the closer we get to an object, the more the muscle tightens in order to focus. This is why when the muscle loses its ability to accommodate, we cannot focus correctly on texts or objects that are closer to us.
PRESBYOPIA SURGERY IN BARCELONA
To correct this defect, there are only two alternatives: the continued use of glasses, which we must continually change the prescription, or surgery, which will solve the problem definitively.
The presbyopia operation in Barcelona at our clinic takes about 10 minutes per eye and consists of replacing the crystalline lens with an intraocular lens that allows us to focus at different distances. Recovery is very quick and the following day the patient is able to see normally and with little discomfort.
TESTS BEFORE PRESBYOPIA SURGERY IN BARCELONA
How is presbyopia surgery performed?
What should I do on the day of surgery?
The most important thing is to fast the night before, including not drinking any water.
After completing the admission procedure, you will be admitted to the surgical area. Once there, you will first be attended to by the anaesthesiologist, who will place an IV to introduce the necessary medication as well as a light sedation. Thanks to this sedation, you will remain in a calm but not completely asleep state, as minimal cooperation from the patient is required.
Once the patient is in the surgical area, the entire eye area is sterilised, the eye is covered with a size and both an anaesthetic in the form of drops and a more powerful anaesthetic that allows the eye to be completely asleep and not feel any pain at all is inoculated.
The presbyopia operation in Barcelona consists of 4 main steps:
- INCISION: A minimal incision (2.2mm) is made through which the entire operation is carried out.
- OPENING THE CRYSTALLINE CAPSULE: The crystalline lens is made up of crystalline material and a very fine capsule that contains it. In order to fit the intraocular lens, it is necessary to empty the capsule and remove all the crystalline material. To do this, it is necessary to remove part of the capsule by making a hole in the anterior face of the crystalline lens.
- FACOEMULSIFICATION: Through the hole we can insert a small probe that performs three functions: Emit ultrasound, aspirate and irrigate. The ultrasound helps to break up the crystalline lens masses so that they are easier to aspirate and at the same time the loss of the aspirated material must be compensated with serum so that the pressure in the eye remains constant.
- IMPLANTATION OF THE INTRAOCULAR LENS: Once all the crystalline masses have been aspirated, the intraocular lens is implanted inside the capsule. This lens, thanks to its multifocality, has the capacity to allow us to focus at different distances, just as we did with the natural crystalline lens before it lost its focusing capacity.
As soon as the surgery is over, the patient returns to a recovery area where he or she will remain for just a few minutes and then go out on their own.
Will I feel pain during surgery?
As mentioned above, the patient is administered different types of anaesthetics as well as light sedation. This means that the patient does not suffer any pain. In any case, the patient may feel a certain sensation of pressure during the operation, but never pain.
Will I go out with a blind eye?
No. Except in exceptional cases, the patient is discharged with the eye uncovered. Although the visual quality will not be perfect, it is good enough for the patient to walk out on their own.
AFTER PRESBYOPIA SURGERY IN BARCELONA
What is the postoperative period for presbyopia like?
What should I do and what should I not do after surgery?
Immediately after the operation, an initial check-up visit is carried out to check that the lens is perfectly positioned and to make an initial assessment of the patient’s visual quality. Obviously, at this first check-up the quality will be limited, mainly because the pupil is still dilated.
The only thing the patient is not allowed to do on the day of the operation is to drive. This is because he/she is still under the effects of sedation and it would be dangerous as he/she may become drowsy.
Apart from this, the patient can practically lead a normal life, although it is advisable not to carry any weight for the first few days.
When will I start to be able to see properly?
There are many factors that can vary the length of time after presbyopia surgery in Barcelona: initial prescription, healing capacity, age… But, in general, after about 10-15 days your vision will be practically perfect.
